Antenatal care in The Gambia: Missed opportunity for information, education and communication

Antenatal care provides an opportunity to inform and educate pregnant women on a variety of issues related to pregnancy, birth and parenthood. The aim of this exercise is to equip them to make appropriate choices that will contribute to optimum pregnancy outcome and care of the newborn [1]. This concept has made antenatal education programmes a standard component of antenatal care worldwide [2].

There has been controversy about the impact of antenatal education on pregnancy outcome [3]. However, a recent synthesis of experience with information, education and communication (IEC) makes the point that it works [4]. In other words, an appropriate strategy of IEC leads to or reinforces desirable attitudes and behaviour.

Educated women have better pregnancy outcome compared with uneducated women [5, 6]. This may be partly because they are better informed and make better choices. Literacy among women in many developing countries is low and there are socio-cultural beliefs and practices with adverse effects on pregnancy and birth even among educated women [7]. The "Three Phases of Delay Model" highlights the importance of IEC in the prevention of maternal death by describing the sequence of events from late recognition of danger signs to maternal death [8]. Therefore, an appropriate programme of health literacy or behaviour change communication is highly desirable.

In The Gambia, over 90% of pregnant women visit the antenatal clinic at least once and 70% attend four or more times [9]. This high antenatal coverage and relatively high frequency of visits provides an excellent opportunity for information, education and communication. The principal guiding documents for the delivery of maternity services in The Gambia show that the provision of information, education and communication is a major component of antenatal care [10–12]. The IEC strategy was first articulated in the early 1990s but has undergone revisions in line with emerging needs. The strategy is to inform and educate pregnant women on a variety of topics including nutrition, malaria, STIs/HIV/AIDS, danger signs of pregnancy and delivery, and care of the newborn. Furthermore, antenatal care providers are expected to engage in dialogue with pregnant women to develop appropriate and individualized delivery plans based on the concept of birth preparedness and complication readiness [12]. This strategy should be implemented routinely in all antenatal clinics.

Despite the foregoing, a recent qualitative study of maternal deaths suggested that low levels of awareness of danger signs of pregnancy and delivery contribute to continuing high maternal mortality ratios in the country [13].

To further explore this issue, we undertook a study to: (i) determine the experiences of pregnant women with antenatal IEC; (ii) determine their levels of awareness of danger signs during pregnancy and delivery; and (iii) compare experiences and levels of awareness between pregnant women attending urban and those attending rural antenatal clinics in the largest health division in The Gambia. We sought to compare urban and rural antenatal clinics because maternal mortality ratios in rural areas were two times higher than in urban areas in the most recent national maternal mortality survey [9]. This data will be useful for reinforcing or modifying behaviour change communication for pregnant women as part of an overall strategy for achieving the country's Millennium Development Goal for Maternal Health.

The Western Health Division, one of six health divisions, comprises three local government councils – Banjul, Kanifing and Brikama. It covers 17.3% of the geographical area of the country but accommodates 55% of the national population [14].

Most antenatal care is provided through government facilities (80–85%) and Non-Governmental Organizations (15–20%). Less than 3% of pregnant women receive antenatal care at private facilities [9]. Registration at a public sector antenatal clinic depends on place of residence. There are six base antenatal clinics in urban areas and five base antenatal clinics in rural areas in Western Health Division. Urban or rural status was assigned based on definitions laid down by the Central Statistics Department of The Gambia [14]. Antenatal clinics open on week days from 8.00 a.m. to 2.00 p.m. and are led by trained midwives. Pregnant women are usually given monthly appointments until 28 weeks gestation, two-weekly appointments until 36 weeks and then weekly appointments until birth. The programme of activities for each clinic session includes a health talk; assessment of pregnant women through history taking, examination and laboratory tests (as indicated) and; provision of tetanus toxoid immunizations and iron/folate supplementation. Health talks are intended to cover nutrition, malaria, STIs/HIV/AIDS, danger signs of pregnancy and delivery, family planning, breastfeeding and care of the newborn. Other management and/or referral take place as indicated. In addition to the above routine, services to prevent parent to child transmission of HIV were offered at two of the facilities as a pilot programme. Staff at these facilities received additional training in order to provide the service. At some base clinics, staff "trekked" to outreach posts to conduct antenatal clinics for parts of their catchment population.

We adapted the Antenatal Client Exit Interview and Antenatal Record Review questionnaires in the Safe Motherhood Needs Assessment (SMNA) Kit [15]. The questionnaires were translated into two local languages (Mandinka and Wolof) and back-translated to ensure consistency.

To achieve a 95% confidence level with a 10% confidence interval, we required a sample size of 192 pregnant women based on an estimated number of 30,000 maternities per year in Western Health Division [15]. Since we intended to compare pregnant women at rural and urban clinics, we determined the sample size for rural and urban women separately giving a desired sample size of 384 (192 rural and 192 urban). We aimed to interview 50 pregnant women at large (busy) antenatal clinics and 25 pregnant women at smaller centres for proportional representation. If there were more women than required at the clinic, systematic random sampling was done. If there were fewer women than required, all were selected and a second visit was made to the clinic to complete the required number.

All pregnant women attending the antenatal clinic when the interviewers were present were eligible to participate. Pregnant women who had emergency conditions were excluded. Individual women were approached, given information regarding the purpose of the study, invited to participate, assured of confidentiality and reassured that opting out would not compromise the care they would receive. Out of 459 women who were approached, 457 participated in the survey. The two who opted out did not give any reasons. The high response rate is not surprising because surveys are common among women of reproductive age in The Gambia. AH and LESJ interviewed the selected women individually and in private at the end of their antenatal clinic consultation. Interviews began in the morning and continued into the afternoon. The study took place in November and December 2004.

The differences between women attending urban and rural clinics were assessed using the Chi-square test. Relative risks with 95% confidence intervals are presented.

The study was approved by the Department of State for Health and Social Welfare, Banjul. The pregnant women who participated gave individual informed consent.

The results of this study show that although a large proportion of women attending antenatal clinics did so repeatedly, they were not benefiting from effective information, education and communication which together form one of the primary purposes of antenatal care. Ninety percent of those interviewed had attended the antenatal clinic more than once and 52% four or more times. However, most of them (70.5%) said they spent 3 minutes or less with the antenatal care provider and less than 40% could recall being informed or educated about important subjects such as diet and nutrition, care of the baby, family planning, place of birth. An even smaller proportion (19.3%) could recall being educated about what to do if there was a complication.

One of the lessons learned from the Safe Motherhood Initiative is that community involvement is a key requirement for sustainable reduction of maternal mortality [16]. However, individual women, families and communities need information and education to be empowered to contribute positively to making pregnancy safer. Therefore, the large proportion of pregnant women in this study who reported that they were not informed or educated about important issues is of concern.

We observed that pregnant women were least likely to recall having received the IEC that related to the recognition of danger and response to pregnancy-related problems. In a study of women 6–12 months after giving birth in another health division, Walraven et al found even lower levels of antenatal education on danger signs and complication readiness [17]. This low level of awareness of danger signs contributes to a failure to obtain adequate care in time and hence, maternal death in The Gambia [13]. There was even less awareness about danger signs for the unborn child.

Information, education and communication require time. The new antenatal care model recommends 30–40 minutes for the first visit and 20 minutes for subsequent visits to carry out all activities including individual IEC [18]. However, most women said they spent 3 minutes or less with their provider. Communicating effectively under this circumstance would be an enormous challenge and could explain the poor provider-client interaction. It was not surprising that in this "rushed" scenario very few women asked questions. On the other hand, it is encouraging that 95% of women understood the answers given to the questions they asked. Direct observation in Nepal revealed that an average of only one minute was spent on counseling [19]. Little attention was also paid to danger signs and complication readiness with communication flowing mostly in one direction from health worker to pregnant woman. Although, the health system in Nepal is probably different from ours, it suggests that the challenge to provide adequate antenatal IEC is not unique to our setting. On the other hand, the new antenatal care model also recommends fewer routine antenatal visits with the expectation that this would give providers more time to spend communicating effectively with clients.

Staff shortages are a major constraint in the delivery of health services in The Gambia but midwives are particularly affected by excessive workloads [20]. Since each midwife must attend to a relatively large number of women in a defined period, the provision of IEC may be given less priority. Even where there are adequate numbers, staff training, attitudes, supervision and incentives would be important determinants of the quality of the services that are delivered. We did not assess these issues but believe that they would be important for planning and organization of services.

There are efforts to improve the human resource situation but in the short term, an effective IEC strategy is needed. Traditionally, IEC has been provided at the antenatal clinic level. In view of the human resource constraints and the need to reach a wider audience, we propose a strategy that provides IEC through the mass media – addressing various issues and encouraging women to ask questions at the antenatal clinic. This has several advantages. A uniform message will be disseminated, it will reach non-pregnant women who will be better informed and able to make better choices early on when they become pregnant (such as early attendance which is particularly important for effective intermittent preventive treatment of malaria). These messages will also reach men (who are influential in maternal health) to encourage positive participation as partners in making pregnancy safer. Cultural perceptions at family and community levels influence how the woman, family and community respond to pregnancy-related complications [15]. By using the mass media, family members and the community as a whole would also be reached with messages that encourage positive attitudes and participation. This is more consistent with intentions of the National Reproductive Health Policy [11].

Ensuring messages reach the target audience is a concern. However, there is recent positive experience in the country with the use of radio for IEC for increasing awareness and knowledge of HIV/AIDS [21]. In Guatemala, clinic and population-based surveys demonstrated that pregnancy-related radio messages increased awareness of danger signs in pregnancy and were an important complement to clinic-based education [22].

The nationwide Maternal Mortality Survey showed that women in rural areas were at increased risk of maternal death [9]. However, the reported provision of IEC was similar in both urban and rural antenatal clinics and where differences occurred, women attending rural antenatal clinics performed better. Thus, the higher risk of death among rural women was not because they were less likely to recognize danger compared to women in urban areas. A possible explanation is that delivery services are less readily available to rural women compared to urban women. In rural communities, access to antenatal services is enhanced through outreach ("trekking") clinics. Health workers from designated base clinics travel to the communities on specific days to provide antenatal services and return to their base. For delivery, women in these rural communities have to travel to the base clinic. Thus, the distance barrier has been overcome for antenatal services but not for delivery services. This is a critical issue since most complications that lead to maternal death occur around the time of delivery.

Pregnant women who do not have adequate and appropriate information about pregnancy and childbirth would be ill-equipped to make choices that will contribute to their own well-being. Delivering carefully developed messages through the mass media, especially the radio is an attractive and feasible strategy that has proven successful with HIV/AIDS in the country. Another vital part of the strategy would be to clearly identify the barriers to individual counseling at the clinic level and institute appropriate interventions to ensure that the peculiar circumstance of each pregnant woman is dealt with.

On the other hand, pregnant women would be unable to make optimal use of the information they have been provided if services are not readily available. Therefore, improving access to services that they have been advised to make use of is vital. In our context, this would mean improving the access to skilled attendance at delivery particularly for rural women.

We believe these steps would contribute to meeting the United Nations millennium development goals for maternal and newborn heath as well as for gender equality and empowerment of women in The Gambia.
